A profoundly beautiful composition by Carla Bley, brought to life patiently and selflessly by Paul Bley, John Surman, Bill Frisell, and Paul Motian. Listening to this feels a bit like entering a slow-motion dreamworld where the laws of physical reality (such as gravity) are flexible and open to creative reinterpretation. Sublime. It reminds me of a quote by Charles Mingus: "Making the simple complicated is commonplace; making the complicated simple, awesomely simple, that's creativity."
